Elon Musk was apparently excited enough about Tesla Inc.'s prospects in China that he was moved to dance, just as shares of the maker of electric cars hit new highs.

The chief executive officer awkwardly waltzed across a stage at Tesla's new factory outside of Shanghai on Tuesday during an event to hand over the first Model 3 sedans to the public. Musk, 48, also elaborated on previously announced plans to produce the upcoming Model Y crossover at the plant.

"Ultimately, Model Y will have more demand than probably all of the other cars of Tesla combined," Musk said, reiterating a prediction made during the company's last earnings call.
